Small Arms Collimators
Increasing First-Round Hit Ratios to
Improve Soldier Lethality and Confidence
Realities of Today’s Battlefield
Soldiers are changing sights frequently to
meet mission requirements/ environments.
Repeatability of sights following removal
and re-mounting is questionable.
The operational environment often does not
allow soldiers to fire to confirm zero and/ or
re-zero, if necessary.
Urban environment, enemy tactics, and
presence of non-combatants make precision
engagement critical.
Francis Barker Small Arms Collimator (SAC)
The Francis Barker SAC is a precision
optical device that allows soldiers to
confirm zero and/ or re-zero weapons in
the field, to a high level of accuracy,
without live fire.
They are manufactured and calibrated
very precisely in order to ensure that any
collimator can be used on any like
weapon with the exact same results/ level
of accuracy.
SACs work with iron sights, optical sights,
and night vision sights. They are
available for assault rifles, submachine
guns, machine guns, sniper rifles, and
grenade launchers.
Laser collimators are available for use
with visible and IR laser aiming systems.
Key Features
Accurate: sub-MOA accuracy
(0.25 mils, 2.5cm@100m).
Repeatable: any collimator can be used on any like
weapon system with the same degree of accuracy.
Passive: does not emit light or any other signature
and does not require a down-range target.
Simple: easy to use with very little training. No
‘master weapon’ is needed. No adjustments or
maintenance. No batteries.
Proven: SACs have been in use for more than a
decade by British and other military forces with
outstanding results.
Key Benefits
•
•
Adjust or confirm zero on weapon systems in under one minute:
– after changing sights;
– after changing weapons;
– during pre-combat checks, or;
– at snipers’ Final Firing Position (FFP).
Reduced range time and ammunition requirements for initial
zeroing.

Instructions for Use
Establishing Personal Zero Position (PZP):
1.
ENSURE that the weapon is CLEAR.
2.
If possible, apply a light coat of oil to the collimator spigot.
3.
Carefully insert the spigot into the barrel of the weapon.
The collimator’s rubber buffer should lightly contact the
end of the barrel.
4.
Take up a normal firing position.
5.
Rotate the SAC to vertical position (as exact as possible).
6.
Adjust sight to exact center/ initial zero position of SAC grid.
7.
Remove the SAC and conduct standard live fire zero
procedures.
8.
Repeat steps 1-5.
9.
Note exact position of sight on SAC grid.
10.
Record grid position, type of sight, and range. This is the
shooter’s PZP for that sight and range.

Instructions for Use
Confirming or Re-Zeroing Weapon to PZP:
1.
ENSURE that the weapon is CLEAR.
2.
If possible, apply a light coat of oil to the
collimator spigot.
3.
Carefully insert the spigot into the barrel
of the weapon. The collimator’s rubber
buffer should lightly contact the end of the
barrel.
4.
Take up a normal firing position.
5.
Rotate the SAC to vertical position.
6.
Adjust sight to PZP.
7.
Remove the SAC and repeat to ensure
accuracy.
Conclusion
Small Arms Collimators solve a critical problem by providing
soldiers with complete confidence in their weapons after changing
sights or changing weapons, or after exposing weapons to the
bumps and knocks inherent to infiltration and movement on the
battlefield.
The Francis Barker SAC is superior to any other device in accuracy
and repeatability. Additionally, it is completely passive and does not
require batteries, adjustments, or maintenance.
The Francis Barker SAC improves soldier lethality and safety by
improving accuracy and increasing first round hit probabilities.
